Aeonium haworthii ‘Tricolor’ (syn ‘Kiwi’) – This native of the Canary Islands is best grown as a container plant here due to its hardiness. It features pale lemon yellow leaves with inset olive green shadings and contrasting margins of reddish-pink. These eventually form stalked rosettes, with yellow flowers being produced in summer. Grows 2-3′ high by 2′ wide. Zone 9.
Echeveria shaviana – This tender succulent features powdery blue to silvery-blue foliage (with purple undertones) with distinct thin undulated edges. When grown in full sun pink margins may appear, although there are cultivars (such as ‘Pink Frills’) with this attribute. Produces orange-pink flowers on arching wand-like stalks. Grows 6-8″ high by 8-12″ wide. Hardy to zone 9.
Orostachys malacophylla – At a casual glance Chinese Dunce Caps may look like your average Hen & Chick, at least until it flowers. It bears green rosettes that produce white cone-shaped flower structures when mature. Like Sempervivum, they die after flowering but readily rejuvenate with offsets and by self-seeding. Requires good soil drainage. Grows 4″ high by 6″ wide. Zone 5.
Sedum nussbaumerianum – With a common name of Coppertone Stonecrop you know you can expect some unusual foliar tones. It features jellybean-like fleshly leaves of golden yellow to coppery-orange, often with red highlights. This native of Mexico produces white flowers in early spring and is best overwintered inside in colder regions. Grows 6″ high by 12″ wide. Hardy to zone 9.
Sedum ‘Lemon Ball’ – This hardy stonecrop is very similar to ‘Angelina’ but with brighter chartreuse to lime green foliage and without the orange highlights in winter. The yellow spring flowers don’t show up well against the the leaves but it makes a great accent in mixed containers or border foregrounds. Drought tolerant. Grows 4-5″ high by 10-12″ wide. Hardy to zone 3.
